It it very pretentious and 'all-knowing' and pure nonsense to state that there was nothing before the big bang.

It's a consequence of the math. I'm sure I can solicit some textbook recommendations if you like.

No textbook (math or physics or any science), or scientific theory can prove or even hint at the true beginnings of the universe. What we all read and hear about are theories and speculations and guesses. Until observations are made of the prer-BigBang universe, everything is a theory and the math and science are just guesses about what was before the so-called Big Bang.
